Description
Roasting a blend of pumpkin, sesame, coriander, and cumin seeds at controlled temperatures develops the deep, nutty flavor base of Guatemalan pepian paste.
Technical
During roasting, Maillard reactions between reducing sugars and amino acids generate pyrazines and furans that impart a characteristic nutty‑roasted aroma. Simultaneously, controlled lipid oxidation produces volatile phenolics such as 4‑hydroxy‑2‑nonenal, while heat denatures lipoxygenase and peroxidase enzymes, reducing rancidity and extending shelf life.
